- ### Monolithic and microservice architecture
+
![Monolith and microservices](./files/building-architecture/monolith-microservices_eng.png)
+
+ A monolith is a complete application that contains a single code base (written in a single technology stack and stored in a single repository) and has a single entry point to run the entire application. This is the most common approach for building applications alone or with a small team.
+
+ - Advantages:
+ > - Ease of development (everything in one style and in one place).
+ > - Ease of deployment.
+ > - Easy to scale at the start.
+ - Disadvantages:
+ > - Increasing complexity (as the project grows, the entry threshold for new developers increases).
+ > - Time to assemble and start up is growing.
+ > - Making it harder to add new functionality that affects old functionality.
+ > - It is difficult (or impossible) to apply new technologies.
+
+ A microservice is also a complete application with a single code base. But, unlike a monolith, such an application is responsible for only one functional unit. That is, it is a small service that solves only one task, but well.
+
+ - Advantages:
+ > - Each individual microservice can have its own technology stack and be developed independently.
+ > - Easy to add new functionality (just create a new microservice).
+ > - A lower entry threshold for new developers.
+ > - Low time required for buildings and startups.
+ - Disadvantages:
+ > - The complexity of implementing interaction between all microservices.
+ > - More difficult to operate than several copies of the monolith.
+ > - Complexity of performing transactions.
+ > - Changes affecting multiple microservices must be coordinated.
